It happens because space and time are connected and are a part of the same whole, spacetime. When you move through space, you move through time. When you ripple space, you 'ripple' time so to speak. When you go close to light speed time starts to dilate, and when you hypothetically go faster than light time dilates so much it goes backward, breaking causality.

@gnanay8555

Since the way time is passing depends on the observer and its speed, you can ask yourself if every observer, no matter its speed compared to another one, still sees the same causes before their consequences, like all other observers. You can verify that doing the maths, and you'll find that it's true if no one can go beyond a certain speed. This is the speed of light (or speed limit. Or speed of information).

why would that be any different than your information being destroyed from the Universe point of view? At this point you better fall into a black-hole, or perhaps you become one if you try to go faster, to go faster you need energy, and lots of energy in a small space become a black hole, you lost causality from the Universe, what remains is the quaint Hawking radiation slowly emanating, like information being "deleted", so energy can be conserved.

If you look at your example, but see the orange fabric as *time* instead of space, it can also provide a way to understand how time dilates and stretches and ‘breaks’. If ‘1 minute’ is the length of your favorite sock from end to end, and you *stretch* the sock, well now the ‘beginning’ and ‘end’ of that 1 minute is still at each end of the sock, theres just ‘more time for you to traverse in that minute’ which sounds a lot like time feelings slower as time dilation occurs. And as for going back in time and “getting an answer before you asked the question”, that can be understood as the object/answer/etc moving so quickly thru the medium of spacetime that it can travel to its destination faster than the question its answering. Thats at least how this model made contextualized the above concepts in relation to time, time travel, and time dilation. Does that all sound like a reasonable understanding of what would go on?

This is amazing

Thanks for an important reminder of the limitations of even great analogies and models, both physical and mathematical, that purport to illustrate the essence of real phenomena. If such models are useful at all, they always have limits or boundaries beyond which they break down and they are likely useful for only certain aspects of the modeled phenomenon.

So technically speaking, if we ever observe that self intersecting gravity waves then we might have found the first ever faster than light object in the universe And we would also should be scared as heck because that means something impossibly energetic happened far away in the far past or maybe even far future

We just established that achieving light speed or greater is impossible so there is no scenario where that would happen. You're basically saying if the impossible happens we're screwed, which is a trivial statement.

@@williamhorn411 not impossible, for something to move faster than light it requires infinite energy, something really really hard to do, since infinity is well infinity But we have examples of infinity already, black holes have infinite density, so in conclusion if one infinity exists, why deny another?

@@Zerum69 We don't have any examples of infinity in nature, and by the definition of infinity we should not find any. In physics, the occurance of infinity is basically a universal error message. Yes, you will find that the description of a blackhole is mass with infinite density and infinitely small volume, but this is not an answer to the problem. It is a representation of how much we still don't know about blackholes. Infinity is not a number, and is not containable. It is the concept of something endless, or continuous, therefore you will never reach it because there is no "it" to reach. So at best, this description of "infinitely small volume" is really saying that all of the matter in the blackhole is being crushed further and further down until the death of the blackhole. However, at any given moment in time both the volume and density of the blackhole is finite. Anyway, obtaining infinite energy isn't something "really really hard to do", it is impossible. Even if you assumed the universe is infinite (which is unproven), you would need all the energy in the universe to propell such an object. Which not only would be pointless, but would include the energy of the object you're propelling as well. The law of conservation of mass and energy also falsify this idea as you cannot "cheat" by recursively creating energy. You would also need an infinite amount of time to allow this infinite energy accelerator to infinitely approach the speed of light and you would still never get there. There are solid theories supported by modern physics that suggest sort-of "faster than light travel" solutions, but they only work because you're not actually moving faster than light. These theories include space-tunneling (wormholes), Alcubierre Drive (manipulating local space-time), and probably several more. You can propose that we may discover ground-breaking physics in the future that completely change the scope of what we now think is impossible, but that's about it. Beyond what we know, we cannot know what is possible or impossible. Saying something IS possible because we are unsure is a logical fallacy. The definition of truth is the inability to falsify an investigatable claim, and currently there are many falsifications for true faster-than-light travel.

When being asked a "what if" question, that's a request for a "thought experiment". Any answer that results in statement that "you can't do that" "or that's impossible" is a failure by the person "answering". Of course an honest reply of "I don't know" and "this model can't handle that situation" is acceptable even if they don't answer the question. Steve however did an honest "my model falls apart" reply. Sadly a lot of people online attack the people asking such hypothetical questions or otherwise blow them off. I haven't gone through the comments on Steves videos to see if his audience is doing that, but it happens on so many science sites there are bound to be some.

And honestly I think the ":the whole thing implodes and the drill is ripped from the hand of God" is a perfect simulation of what *would* happen, with the universe violently correcting itself so that what had been faster than the speed of light is no longer

Well, if you ask a "What if" question based on an impossible parameter, the only possible answer is "I don't know". Of course the model can't handle it. Even reality can't handle it. Any explanation attempt is equally invalid.

"To infinity (not beyond)". That's well put :-)

i think that demonstration of spinning the holes faster than the speed of light is a great explanation of how the fabric of space time keeps you bellow the speed limit of light

I'm glad you said "orbit each other" later, since that could be thought of as a correction of "orbit[ing] around each other," which is a redundancy.

Thank for this videos. I really like your explanations. This visualizes 2 black holes with the same gravitational force so the centre of the spin is equal to each other. I am wondering what happens with the waves if you are spinning the wheels with the powerdrill with a slight offset from its rotational centre and one higher wheel (that wheel represents a bigger gravitational force)

When you accidentally rip the Universe

I enjoyed watching you loose control of the drill 🧐 Science!

I really enjoyed the video, thanks. Especially the part that left the topic behind and went into the thoughts about the way how our scientific models change by probing their limitations. By the way, I'm *really* happy that you didn't actually tore the fabric of the universe apart, but just warped and tangled it with a cord drill 😉

I wonder how that model can relate to rotating electric charges generating a magnetic field.

Normal folks: 1080p60 Steve: 1080p50 Me: nice

first of all thanks for the video . i dont know if i can make a precise description but here it is anyway , to have the simulation close to the space if u put 2 spheres filled with colorant and you get them to turn in water, they should be attached to think stick and that one is attached to 2 planetary gears at 180° apart from each others middle one is the rotation entry, i can make a 3D model if this idea interests you , water tank should be big to get the waves generated by the sphere and not the ones resulting from the ones hitting the walls of the tank , dont know if this will work or if there is smaller details that will impact the hole thing , any way i imagine it being something special to see .

Nothing can go faster than speed of light through space. That does not apply to space itself because space can move faster than light. Alcubiere's warp drive achieves that by warping space. It is not moving through space, it is moving space itself.
